Deprecated/obsolete template?

Going off of the WhatLinksHere pages in the "(Main)" namespace (so it excludes user pages/sandbox subpages and talk pages), it seems this template is basically unused, with the exception of an archived Q&A page and a little blurb about the Arc Lich in the Dailies Guide. I'm assuming it's been more or less replaced by the semantic templates. Could we include some sort of "don't use this anymore" header at the top -- I don't know if there is a banner that's all meta and wiki-specific rather than game-specific -- and would it make sense to remove it from the Style Templates category as well?

Yeah I think it sounds reasonable to remove the category for now, but there's no way to properly mark it as deprecated at the moment. I'll think about this a bit.

For the Arch Lich in Dailies Guide (and any others like it), that should be converted to use the new system via #show, but I suspect many of these are links to the template rather than uses of them, so those can just be ignored.
